Real-World Site Resilience Design in Microsoft

*a manual disaster recovery process used to recover from a complete site failure
*not automatic but can be automated.
*goal: make sure you have a copy of data and someone can bring it up
*not just technology: people, process, and the procedures... these along with the technology will allow for successful site resilience
*what is the cost of losing your HA solution? make sure this out weighs the the cost for putting in SR. You can also do SR for dedicated DBs.

*IE has 20 min cache for address, you can set your DNS TTL for OWA down to 5 sec, but you won't get a redirect unless you close out IE and reOpen

*The failback URL, make sure to include failback URL.
